How do I log in to the app after I've added a profile?

All profiles log in with the same e-mail address and password, the one that the account was created with.

When you log in to the app, you will automatically see the profiles that are available. Choose the one that you want to listen or read with.

If you are in the wrong profile, you can always switch by clicking on "Profile" in the lower right corner and then on "Switch Profile".
